Subject: Re: [PATCH] examples/l3fwd: extend NUMA nodes limit beyond 8
Date: Sat, 27 Dec 2025 16:53:19 +0800 [thread overview]
Message-ID: <06d7fffb-558c-4088-8410-8943d12724fe@huawei.com> (raw)
In-Reply-To: <20251226081719.1120313-1-wangliangxing@hygon.cn>
Acked-by: Chengwen Feng <fengchengwen@huawei.com>
BTW: Other examples also defined the NB_SOCKTS (e.g. l3fwd-power/l3fwd-graph/ipsec-secgw),
how about add more commits to fix.
